Here is an optimized example of a client-side V2Ray DNS configuration designed to eliminate latency:
The root cause of slow DNS is almost always one of three scenarios:

"dns": "servers": [ "1.1.1.1", "8.8.8.8", "https://dns.google/dns-query", "localhost" ], "hosts": "domain:google.com": "8.8.8.8" , "clientIp": "1.2.3.4" v2ray slow dns server
CoreDNS is faster and natively supports DoH, gRPC, and caching. ./Corefile :

The primary reason for slowness is often or incorrect routing . If V2Ray is configured to send DNS queries through the proxy tunnel to a far-away server (like a US-based resolver while you are in Europe), the "Round Trip Time" for every single link you click increases significantly.
V2Ray is a tool for constructing versatile proxies to bypass network restrictions. It supports multiple protocols and can be used with various transport protocols, including TCP, WebSocket, and more. DNS (Domain Name System) plays a crucial role in how V2Ray and similar tools operate, as it translates domain names into IP addresses.

V2Ray’s fakedns feature assigns virtual IPs to domains, avoiding DNS lookups for subsequent connections. Near-zero DNS latency after first resolution. Drawback: Incompatible with some strict SNI-based routing.
V2Ray is a powerful framework for bypassing network restrictions. However, many users experience frustratingly slow connection speeds. While most people blame poor proxy servers or network throttling, the actual culprit is often a misconfigured Domain Name System (SNM) setup.
